Product Description

Electric Tube Flange heaters are designed for heating or temperature maintening of liquids, gas or mixture in static or circulation conditions.
The design is based on customer process conditions: fluid to heat (type and properties), in/out temperature, pressure, heat exchange conditions (stagnant or flowing), and environment conditions (ATEX or not, onshore or offshore, etc.).
Flange immersion heaters can be straight or L-shaped.

Specification

Features:

Flange heaters are typically used for larger volume and higher power applications or where ange tank or pipe vessel connections are preferred. Tubular heater elements are brazed or welded to the anges for convenient mounting.
